To all whom it may concern:

Be it known that we, WALTER Scorr and DAVID JOHN Sco'r'r, citizens ofthe United States of America,

and residents of Plainfield, Union county, New Jersey, have inventedcertain new and useful Improvements in Delivery Mechanisms, of which thefollowing is a specification.

Our invention relates generally to delivery mechanisms for sheets ofpaper or other flexible material, and has more particular reference tosheet delivery mechanisms used in printing presses.

In the class of printing machines known as two revolution/*stop cylinderand similar machines, the printed sheets are generally delivered withthe printed side up, sometimes, however, it is desirable to deliver thesheets with the printed side down. Furthermore,

it is frequently desired to change from one style of delivery apparatusto another in the same machine, when doing different classes 'of work. I

The object of our invention is to produce an in1 proved structure of thecharacter described, capable of delivering the sheets with the printedside down, and adjustable so that the sheets 'be delivered either withthe same machine. v A

In carrying 'oi'itthe" above objects; the'invention is characterized by'a reciprocating delivery and means for delivering sheets theretoeitherside up. These latter means preferably take the form of an endlessconveyer. l f Y The invention is further characterized by an endlessconveyer having a gripper frame with grippers for seizing and releasingthe sheet. Any other means instead of grippers could be used for seizingthe sheet and the claims should be so construed. Adjustable means areprovided for driving the said endless conveyer in "either directiondependentiiipon whether the sheet is delivered with the printed side upor down. The grippers or other means for seizing and releasing the'sheetare further adjustable to corre-' spond with the direction ofmovement of the endless conveyer. To open the grippers at the propermoment to seize and release the sheet, there are provided two sets tcams, one seton either-side of the machine whir' cooperate with a rolleron the gi'ipper shaft. Whethe printed side down delivery is used, onecam is mounted adjacent to the upper surface of the end ess conveyer andat the feeding'point of the latter, and another cam is located adjacentto the under surfs of the conveyer at some suitable delivery point. Whenthe printed side up delivery is used one cam is located adjacent to thepder surface of the endless 'conveyer and at the feeding point, whilethe second cam is located also on the underside of the conveyer but atthe forward end at some suitable delivery point.

1 the sheets with the printed side up. Fig. 5'is a plan printed sideupordown'at will in' the The two cams belonging to each set of cams arelocated on the same side of the machine so that all four cams can beretained in position at all times, thereby rendering it necessary onlyto reverse the gripper frame and roller for cooperating with the camswhen changing from one style of machine to another.

In connection with the endless conveyer, we pr0- vide means forconveying the sheets to said conveyer which are adjustableso thatthesheets are delivered either on top or to the underside-0f the saidendless conveyer to correspond to the up or down delivery. Thisconveying means will preferably take'the form of a sheet path or tapespivoted adjacent to the cylinder of the printing press, and adjustablysecured adjacent. to the endless conveyer. 4 The endless conveyercarrying the grippers does not run as fast as the impressioncylinderandsheet con veying means. It is. therefore some times desirable to i ihave the grippers seize the sheet at a point some dis tance away fromthe receiving point, thereby lessening' the force of the sheet as itstrikes against the stop on the grippers, and allowing the sheet to slipor slideonto the endless conveyer. For this reason we mount the camsadjustably so that both the receiving point of' the grippers and thedelivery point are variable.

When the sheet is delivered to the top of the endless conveyer, it isnecessary to have some supporting means for the body of the sheet-asrods or tapes or an endless belt. It is also necessary to providesuitable means for guiding the sheet at the forward end of the endlessconveyer as. the sheet is turned over, and to' provide an adjustablestop to prevent the sheet from being carried with the-grippers after thelatter release the same. Below the endless conveyer we mount areciprocating carriage provided with a roller adapted to unwind acollapsible apron as the sheet is delivered on top of thesame, arid. todeliver the sheet from thence to the receiving table. The parts are soarranged that the same apron can be used whetherwe use the up or downdelivery.

In the accompanyingdrawings wehav embodied our invention in a suitableform, though the invention is not limited to the precise structureshown.

The endless conveyer in the present instance takes the form of endlesschains 6, ,to which motion is imparted by means of the sprockets 7 and8. Mounted on the same shaft with the sprocket wheel 7 is a bevel gear8", meshing with the bevel gear 9 mounted on the upright shaft 10,carrying two bevel gears ll and 12 which are adjustable into and out ofengagement with the bevel gear 13, mounted on the transverse stud l4,and receiving its motion by means of the pinion 15, mesh ing with thegear 16, to which latter motion is imparted in any suitable way. Thegearing "is so arranged that the endless conveyer will make one completemovement to every two'revolutions of the impression cylinder. The bevelgearsll and 12 are so arranged that when one gear is in engagement withthe I gear 13, the other gear is moved out of mesh with the (-onveyer.

Mounted on the chains 6, is a gripping mechanism 17 in the form of acarriage 18, carrying a gripper shaft 19, provided with a plurality ofgrippers 20 which are normally held closed by the spring 21, woundaround the gripper, shaft and fastened to the framework; These grippersare adapted to be opened by means of the arm 22 and roller 23engagingwith the cams 24 and 25. r

The reciprocating carriage 4 is driven in any suitable way, and operatesonce to every two revolutions of the impression cylinder in the same wayas the endless In other styles of machine, these two elements would makeone-complete movement to every impression, or if a collecting cylinderbe used, to every In the present instance, the said reciprocatingcarriage and roller 5 are operated from the. disk 26. carrying the rack27, meshing with the pinion 28, mounted on the shaft 29, meshing withthe sliding rack 31, which is in-engagelnent with the pinion 32, of thereciprocating carriage 4, the said reciprncating carriage also havingthe gears 33 meshing with the stationary racks 34.

35 is the delivery board or,receiving table located bel'owthereciprocating carriage and roller 5.

Intcrposed between the impression cylinder and the endless conveyor isthe conveying means 3, as heretofore noted, adjustable to deliver thesheets either on top or to the underside of the endless conv yer. In thepresent instance this conveying means take the form' of side bars 36,pivoted adjacent to the impression cylindor on the pivot 37, and adaptedto be adjustably secured in the slotted member 38, adjacent to theendless conveyor by means of the bolt 100. i The side bars carry rollersas 39 and 40 mounting tapes 41 for convey- 1 ing the sheet on theimpression cylinder to the endless conveyor.

In Fig. l the parts are shown adjusted so that the sheet will bedelivcred'with the printed side down.

That end of the adjustable conveying means which is adjacent to theendless conveyor is moved to its uppermost position so that the sheetscan pass freely on top of I the said endless conveyer. The bevel gear 12is moved into engagement with the gear 13 so that the endless conveyormoves in the direction of the arrow shown in Fig. 1. The grippingmechanism 17 is so adjusted that it will receive the sheet as it passesfrom the adjustable conveying means to the endless conveyer. is, in thepresent instance, located adjacent at the upper side of the endlesschain, and adjacent to the point of feeding, while the cam 25 is locatedat the underside of The care 24 5 the endless chain, adjacent to thedelivery point. The sheet as it passes from the impression cylinder willtravel over the tapes 41 to the top of the endless conveyer. At thismoment, the gripping mechanism 17 will be at the feeding point of thesaid conveyer andat its upper side, the cam 24 acting to open thegripping mechanism it receives the sheet. As the gripping mechanismtravels forward, the spring 21. will close the said gripping mechanismand hold the sheet securely, causing it to travel over the top-of asuitable support as the endless belt 45. Adjacent to the forward end ofthe said endlessconveyer, and on top of the same, there is a frictionroll or rolls 42 which serve to guide the sheet ,as it is turned aroundby the gripping mechanism, and to confine it against the cylinder 44;Instead of the roll 42, we can employ a guide as 46 adjacent to thecylind or 44. The said cylinder 44 and another cylinder 47 may be usedto carry the endless belt or sheet support. When the gripping mechanism17'has reached the rearward end of the endless conveyer, and at theunderside of the same, the cam 25 will open the gripping mechanism andrelease the sheet. At this moment, the apron 43 will be unwound and thesheet will drop on the same. As the reciprocating carriage and roller 5return, the apron will be rowound and the sheet will drop ,on thedelivery board 35. To stop the sheet at the proper point I- provide anadjustable stop 48 interposed between the endless conveyer and thecollapsible apron. When it is desired to deliver the sheets with theprinted side up, the sheet-path will be adjusted so as to deliverthesheets to the underside of the endlcss convcycr as shown in'Fig. 3. Thegripper frame or carriage 18 will be reversed as indicated in'Fig. 4,and'the roller 23 will engage with the cams 44 and 45 which are bothlocated at the under surface of the endless conveyor, and respectivelyat the feeding point and at the forward end of the endless conveyer andon the other side of the machine from the cams 24 and 25. The bevel gear11 will be moved into engagement with the gear 13, and the gear 12 movedout of mesh with the latter. The sheet, as it comes from the impressioncylinder, will be delivered to the underside of the endless conveyorwhere it is seized by the gripping mechanism which is opened at thatpoint, and be drawn out until the gripping mechanisin reaches the cam45, when the sheet is released. The apron 43 willbe unwound at thistime,

. and will receive the sheet and in turndel iver it to the deliveryboard as it rewinds. Both sets 0f cams 24 and 25 and 44 and 45 canalways be in thef proper position so that when it is desired to changefrom an 'up to a down delivery or vice'versa it is only necessarytoreverse the gripperfrarne or carriage. v To make the cams adjustable, weprovide the same with bolts 49 adjustable in the slots 50 on the framework.
